The phalanx bones, or plural phalanges, are those that form the fingers and toes of your hands and feet.

Phalanx-- Any of the digital bones of the hand or foot.

• There are four bones in the thumb. one at the top one at the bottom and one at either side.
• The bones in the thumb consist of: distal phalanx; proximal phalanx; metacarpal; carpal bones (carpometacarpal joint (CM).

The bones of the fingers are carpals (hence carpal tunnel syndrome), and the bones in-between the wrists and fingers are metacarpals. The bones of the toes are tarsals and the bones in-between then toes and ankles are metatarsals. Huzzah!
